This seems lo be a very rare plant. Harlweg found bui a single specimen , tbe 

 panicle of whicli was nine feet long. The flowers are as in falcipetolura; their co- 

 lour seems to be purple, judging from the dried specimen.

 Cordillera near Loxa. 



Of ihis a single plant was found by Hartweg , wilh a flower stem 9 feet long. It 

 is very near 0. corynephorum , but ihe flowers are more than twice as large, the lip 

 has quite a diffcrcni form and the column has two shorl spreading arms near the 

 base , of which no trace is to be found eithcr in Poppigs figure or in Matthew's 

 drawing in our possession.
